* Asus ROG STRIX X870E-E Gaming Wifi (ACL4082) - No audio from rear microphone [not found] <189b34c33673d400-webhooks-bot@alsa-project.org> @ 2026-03-09 15:08 ` GitHub issues - edited 0 siblings, 0 replies; 3+ messages in thread From: GitHub issues - edited @ 2026-03-09 15:08 UTC (permalink / raw) To: alsa-devel alsa-project/alsa-ucm-conf issue #718 was edited from cristian-tamblay: The Rear Microphone is detected as Line In when I plug in my mic. There is no sound from the microphone. Motherboard: Asus ROG STRIX X870E-E GAMING WIFI Audio Device: ALC4082 USB ID: 0b05:1b9b Distro: Ubuntu 24.04 Window Manager: Gnome-Shell Before patching UCM locally, Linux exposed only generic USB audio profiles and the rear jack behaved like line input. After adding USB ID `0b05:1b9b` to the UCM matching rules, the device now loads proper `HiFi` profiles and exposes `Microphone`, `Front Microphone`, and `Line Input` sources, but the rear microphone still does not record actual voice audio. Recording now produces at most a small click/pop when capture starts, but no usable microphone signal. I added `1b9b` in two places. 1) `/usr/share/alsa/ucm2/USB-Audio/USB-Audio.conf` 2) `/usr/share/alsa/ucm2/USB-Audio/Realtek/ALC4080-HiFi.conf` `lsusb | grep -i audio` `Bus 003 Device 004: ID 0b05:1b9b ASUSTek Computer, Inc.
